Startup funding rounds refer to the various stages of financing that a startup goes through in order to grow and expand. These rounds can include bootstrapping, personal savings, credit cards, friends and family rounds, angel investors, venture capital rounds, crowdfunding, debt financing, and government grants. Each round serves a specific purpose, such as product development, market research, scaling, market expansion, operational infrastructure, acquisitions, preparing for IPO, and further scaling. The goal of these funding rounds is to provide the necessary capital for the startup to achieve its business objectives and reach its full potential.
